ltdl: fix a long standing duplicate `-ldl' bug in the link line.
* m4/ltdl.m4 (LT_LIB_DLLOAD): Save contents of LIBS before
calling AC_SEARCH_LIBS, which prepends to LIBS by default, and
restore afterwards. We set LIBADD_DLOPEN and LIBADD_SHL_LOAD
so that dynamic loader libraries can be added selectively only
where they are needed.
* NEWS: Update.
